Gastritis: symptoms and treatment in Luxembourg

When the stomach lining flares up

Gastritis is an inflammation of the inner lining of the stomach, causing burning, pain in the pit of the stomach, nausea or a feeling of heaviness after meals. It can be acute, appearing suddenly and settling within days, or chronic, building up over months or years, sometimes with barely noticeable symptoms. A general practitioner can manage a typical episode of gastritis; a gastroenterologist becomes involved when symptoms persist, are severe, or need further investigation.

The most common causes

Several factors can irritate the stomach lining until it becomes inflamed. Taking anti-inflammatory drugs, especially repeatedly or over a long period, is among the most frequent causes of acute gastritis. Alcohol, in excess or used repeatedly, directly irritates the stomach lining. The bacterium Helicobacter pylori — the same one involved in most stomach ulcers — is also a major cause of chronic gastritis: it settles durably in the lining and keeps a low-grade inflammation going, sometimes for years without clear symptoms. Significant stress, particularly during hospitalisation or serious illness, can also trigger acute gastritis, as can certain rarer autoimmune conditions.

Gastritis, ulcer, reflux: not the same thing

These three conditions affect the same region and share overlapping symptoms, but they are not identical. Gastritis is a diffuse inflammation of the stomach lining, without necessarily a localised sore. An ulcer is a specific, deeper sore that most often forms on ground already weakened by gastritis — the two are in fact often linked, particularly through Helicobacter pylori. Gastro-oesophageal reflux, on the other hand, is the rise of stomach acid into the oesophagus, causing burning that travels up towards the throat rather than a localised stomach pain. Only an examination — endoscopy — can reliably tell these situations apart, as symptoms alone are not always enough to decide.

What helps day to day

During a gastritis flare, eating smaller, more frequent meals, avoiding alcohol, tobacco and anti-inflammatory drugs, and limiting very spicy or fatty foods can ease symptoms while the lining heals. Acid-reducing treatment is often prescribed to speed up relief and allow the lining to recover. When Helicobacter pylori is the cause, a targeted course against the bacterium is needed to prevent inflammation from settling in long term.

When further investigation is needed

Endoscopy is not routine for a single, typical episode, especially in a younger person. It becomes useful when symptoms persist despite treatment, recur regularly, come with warning signs such as weight loss, repeated vomiting or signs of digestive bleeding, or occur for the first time after age 50. It also confirms the presence of Helicobacter pylori and rules out other causes.

Care in Luxembourg

The general practitioner manages most typical acute gastritis cases, with symptomatic treatment and lifestyle advice. The gastroenterologist steps in for chronic forms, resistant symptoms, or when endoscopy is indicated to confirm the diagnosis or test for Helicobacter pylori. Consultations and tests are covered by the Caisse nationale de santé under the usual rules, detailed on cns.lu. Well identified and treated, gastritis most often resolves favourably without complication.

Reducing the risk of recurrence

Once the episode has settled, a few precautions limit the risk of another flare: spacing out or avoiding anti-inflammatory drugs when an alternative exists, moderating alcohol, not smoking, and eating at a regular pace rather than skipping meals and then overeating. For someone who needs anti-inflammatory drugs long term for another condition — arthritis, rheumatism — the doctor can add stomach protection from the outset, a simple precaution that prevents many complications. Finally, if gastritis linked to Helicobacter pylori has been confirmed in one family member, it may be worth mentioning to the doctor, as the bacterium sometimes spreads within the same household.

A word on over-the-counter relief

Antacids and acid-reducing tablets bought at the pharmacy can bring quick relief for a mild, occasional flare, but relying on them repeatedly without medical advice risks masking a problem that needs proper treatment, such as Helicobacter pylori infection. If you find yourself reaching for the same box every few weeks, that pattern itself is worth mentioning at your next consultation rather than working around it indefinitely.

Diet during recovery

There is no single gastritis diet that suits everyone, but a few general habits tend to help: eating slowly, avoiding very large meals late at night, and paying attention to which specific foods reliably trigger discomfort rather than following a long list of generic restrictions. Many people find their own tolerance returns to normal once the inflammation has healed, so overly strict, long-term dietary rules are rarely necessary once the underlying cause has been treated.
